  1. 41. Carbon Flows in Sweden : A Substance Flow Analysis of anthropogenic carbon flows

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Sofia Gunnarsson; [2022]
    Keywords : Carbon; Carbon Flow; Carbon Stock; Substance Flow Analysis; Sweden; Industrial Ecology; Anthropogenic;

    Abstract : Carbon (C) is an essential element for all life. However, modern livestock keeping and usage of carbon through burning of fossil fuels are resulting in increased concentrations of carbon dioxide and methane in the atmosphere, two important greenhouse gases (GHG). READ MORE

  3. 42. Development of a new simmer ring : A collaboration between KTH and Trangia AB

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Oliver Holmquist; Erica Alfredsson; [2022]
    Keywords : ;

    Abstract : Det här kandidatarbetet har som syfte att ta fram en ny lösning åt Trangia för att reglera värmen i deras spritbrännare. Ett antal problem skulle lösas. Bland annat ska användaren inte ska kunna bränna sig, lösningen ska vara liten och lätt, samt optimeras för tillverkning. READ MORE

  4. 43. Chemical Kinetic Modeling of the Combustion of NH3/H2 and NH3/syngas Fuel Mixtures Using a Large Amount of Experimental Data

    University essay from Lunds universitet/Kemiska institutionen

    Author : Andras Szanthoffer; [2022]
    Keywords : Ammonia combustion; Detailed chemical kinetic mechanisms; Quantitative mechanism comparison; Local sensitivity analysis; Chemical Physics; Chemistry;

    Abstract : Nowadays, due to the global climate change, it is extremely important to find alternative fuels to reduce the utilization of fossil fuels and the emission of air pollutants such as carbon dioxide (CO2), hydrocarbon pollutants, and soot. Ammonia (NH3) is a promising carbon free fuel candidate that can store and transport renewable hydrogen (H2) energy. READ MORE

  5. 44. Electrified Reforming of Biogas to Hydrogen for Industrial Furnaces with Negative Carbon Emissions: A Feasibility Study

    University essay from KTH/Materialvetenskap

    Author : Moa Bertling; Agnes Milstig; [2022]
    Keywords : ;

    Abstract : The steel industry emits large amounts of carbon dioxide, the main emissions are produced inthe process of heating up steel in industrial furnaces of electric arc furnaces (EAF). The purposeof this project was to propose and evaluate a process of reforming biogas to hydrogen to use asfuel for industrial furnaces and result in carbon neutral or carbon negative emissions.

  6. 45. Extension of low voltage distribution by pure DC or mixed AC/DC parts for integration of solar PV and EV charging

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Sofie Jiang; [2022]
    Keywords : LVDC; LVAC; solar PV system; electric vehicle charging station; IKN-regulation; distribution system; RES integration; LVDC; LVAC; solceller; elfordon; laddstolpar; IKN-regelverk; distributionsnät; förnyelsebara energikällor;

    Abstract : This work examines the local distribution system in two residential areas in two Swedish towns, Oxelösund and Karlskrona, and studies how integration of PV systems and electric vehicle (EV) charging stations (CS) will affect the present distribution system. The research questions focus on the economic feasibility of a LVDC system, how it compares to a traditional LVAC (low voltage alternating current) system from an economic and technical perspective, and the possibilities a LVDC system brings to other DC component applications.
